DD, you are totally wrong - definitely not management. I have had a case on my aircraft where handcuffs were required. Police at an overseas location interviewed the offender then released him. Qantas management were furious but justice was served when he entered Australia 6 months later - he was arrested and charged.
Management stated that they would always prosecute as the effect on other pax was severe and they wanted to deter any repeat offences.
Clarrie, good point but the crew could have completed the sworn statements on return from Singapore.
